The remote host is vulnerable to an HTML injection attack.
The remote server is a WebSphere server. This version is reported to be vulnerable to an HTML injection flaw. An attacker exploiting this flaw would need to create a custom request that utilized custom 'Expect' headers and be able to convince unsuspecting users to launch the URI. Successful exploitation would result in an attacker gaining access to confidential client data.
Upgrade or patch according to vendor recommendations.
